THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

• Turn the television or radio antenna until the interference stops.

• Move the equipment to one side or the other of the television or radio.

• Move the equipment farther away from the television or radio.

• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

1Overview

The Cisco Nexus Fabric Extenders (FEXs) support 100M/1G/10G Ethernet environments while allowing transparent migration to 10-Gigabit Ethernet virtual machine aware unified fabric technologies. The Cisco Nexus FEXs behave as remote I/O modules for a parent Cisco Nexus switch. The FEX is an extension of the parent Cisco Nexus switch fabric, with the FEX and the parent Cisco Nexus switch together forming a virtual modular system.

A Cisco Nexus FEX forwards all the traffic to the parent Cisco Nexus Switch over 10/40-Gigabit Ethernet uplinks. Passing all traffic to the parent switch allows traffic forwarding to be controlled according to policies established on the parent Cisco Nexus switch with a single point of management.

This chapter describes the Cisco Nexus Fabric Extenders (FEXs) and includes these sections:

Chapter 1 Overview Power Supply and Fan Modules






Power Supply and Fan ModulesEach FEX chassis supports one or two power modules (one for operations and one for redundancy) and 1, 3, or 4 fan modules (depending on the FEX model). If the chassis has only one power supply, make sure that there is a blank module (N2200-P-BLNK) installed in the unused power supply slot to preserve the designed airflow.

Each FEX chassis supports power supply and fan modules that have either port-side intake or port-side exhaust airflow.

Caution All of the power supply and fan modules in the same chassis must have the same airflow direction and the cold air intake for the chassis must be located in a cold aisle or else the switch can overheat and shut down.

Port-side intake modules have red coloring and port-side exhaust modules have blue coloring. Power supply coloring is displayed on the module release latches, and fan module coloring is displayed as either a stripe on the front of the module or as the color of the module handle.

Note Some older power supply and fan modules use black stripes for port-side intake airflow and no stripe for port-side exhaust airflow.

You can hot swap a power supply module as long as there is another power supply module functioning in the chassis. You can hot swap a fan module in a chassis with multiple fan modules as long as the other fan modules are installed and functioning. You can hot swap a fan module in a chassis with a single fan module as long as you replace it within 60 seconds.

For the power supplies supported by each FEX chassis, see Table 1-5. For the fan modules supported by each FEX chassis, see Table 1-6.

Chapter 2 Installing a Cisco Nexus Fabric Extender Preparing for Installation

Preparing for InstallationThis section includes the following topics:

• Installation Options, page 2-2

• Airflow Considerations, page 2-2

• Chassis Weight, page 2-3

• Installation Guidelines, page 2-3

• Required Tools and Equipment, page 2-4

• Unpacking and Inspecting the Cisco Nexus Fabric Extender, page 2-5

Installation OptionsThe Cisco Nexus FEX can be installed using the following methods:

• In an open EIA rack, using the following items:

– The rack-mount kit shipped with the device

– The EIA Shelf Bracket Kit (an optional kit, purchased separately)

• In a perforated or solid-walled EIA cabinet, using one of the following:

– The rack-mount kit shipped with the device

– The EIA Shelf Bracket Kit (an optional kit, purchased separately)

For instructions on installing the device using the rack-mount kit shipped with the device, see the “Installing the Cisco Nexus Fabric Extender Chassis in a Cabinet or Rack” section on page 2-6.

Note The optional EIA Shelf Bracket Kit is not provided with the device. To order the kit, contact your device provider.

Airflow ConsiderationsAirflow through the Cisco Nexus FEX is from the port side exhaust to the back or the back to the port side exhaust. To ensure proper airflow, follow these guidelines:

• Position the chassis so that its air intake side (port side exhaust side for port side exhaust airflow or back side for port side intake airflow) is in a cold aisle. Otherwise, an overtemperature condition can occur and the system can shut down.

• Avoid having the air intake where other systems exhaust air.

• Due to the shallow depth of the Cisco Nexus FEX, it is also possible for air to recirculate across the top and bottom of the chassis in a partially populated rack.

• Make sure that the fan tray and power supply modules all use the same direction of airflow. All of the modules should have no black stripe (port side exhaust airflow) or all of the modules should have a black stripe (port side intake airflow).



Note If the switch is powered up with modules that have different airflow directions, you need to shut down the switch before replacing the modules with the wrong airflow direction.

• Maintain ambient airflow throughout the data center to ensure normal operation.

• Consider the heat dissipation of all equipment when determining air-conditioning requirements. When evaluating airflow requirements, take into consideration that hot air generated by equipment at the bottom of the rack can be drawn in the intake ports of the equipment above.

• If you mount a chimney type of rack, avoid mounting it in a way that is contrary to the direction of flow in the chimney, where the chimney overpowers the system fans.

Chassis WeightWhen lifting the system, follow these guidelines:

• Disconnect all power and external cables before lifting the system.

• Have two people lift the system. The Cisco Nexus FEXs can weigh up to 18.5 pounds (8.4 kg).

• Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.

• Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.

Installation GuidelinesWhen installing the Cisco Nexus FEX, follow these guidelines:

• Plan your site configuration and prepare the site before installing the chassis. Appendix G, “Site Preparation and Maintenance Records,” lists the recommended site planning tasks.

• Record the information listed in Appendix G, “Site Preparation and Maintenance Records,” as you install and configure the device.

• Ensure that there is adequate space around the device to allow for servicing the device and for adequate airflow (Appendix B, “Technical Specifications,” lists airflow requirements).

• Ensure that the air-conditioning meets the heat dissipation requirements listed in Appendix B, “Technical Specifications,”

• Ensure that the chassis air intake will be located in a cold aisle and away from the exhaust of other systems.

• Ensure that all of the fan tray and power supply modules have the same direction of airflow as follows (the switch supports only one airflow direction for all modules):

– Port-side intake airflow modules have black stripes.

– Port-side exhaust airflow modules have no colored stripes.

Note If the switch is powered up with modules that have different airflow directions, you need to shut down the switch before replacing the modules with the wrong airflow direction.



• Ensure that the cabinet or rack meets the requirements listed in Appendix A, “Cabinet and Rack Installation.”

Note Jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on page C-9.

• Ensure that the chassis is adequately grounded. If the device is not mounted in a grounded rack, we recommend connecting both the system ground on the chassis and the power supply ground to an earth ground.

• Ensure that the site power meets the power requirements listed in Appendix B, “Technical Specifications,” If available, you can use an uninterrupted power supply (UPS) to protect against power failures.

Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems such as the Cisco Nexus FEX, which can have substantial current draw fluctuations because of fluctuating data traffic patterns.

• Ensure that circuits are sized according to local and national codes. For North America, the power supply requires a 15-A or 20-A circuit.

Caution To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the device are within the current ratings for the wiring and breakers.

• Use the following screw torques when installing the device:

– Captive screws: 4 in-lb

– M3 screws: 4 in-lb

– M4 screws: 12 in-lb

– 10-32 screws: 20 in-lb

– 12-24 screws: 30 in-lb

Required Tools and EquipmentBefore beginning the installation, ensure that the following items are ready:

• Number 1 and number 2 Phillips screwdrivers with torque capability

• 3/16-inches flat-blade screwdriver

• Tape measure and level

• ESD wrist strap or other grounding device

• Antistatic mat or antistatic foam

The following additional items (not found in the accessory kit) are required to ground the chassis:

• Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the Cisco Nexus FEX to proper grounding facilities

• Crimping tool large enough to accommodate girth of lug



• Wire-stripping tool

Unpacking and Inspecting the Cisco Nexus Fabric Extender

Caution When handling device components, wear an ESD wrist strap and handle modules by the carrier edges only. An ESD socket is provided on the chassis. For the ESD socket to be effective, the chassis must be grounded through the power cable, the chassis ground, or the metal-to-metal contact with a grounded rack.

Tip Keep the shipping container in case the chassis requires shipping in the future.

Note The device is thoroughly inspected before shipment. If any damage occurred during transportation or any items are missing, contact your customer service representative immediately.

To inspect the shipment, follow these steps:

Step 1 Compare the shipment to the equipment list provided by your customer service representative and verify that you have received all items, including the following:

• Print documentation

• Grounding lug kit

• Rack-mount kit

• ESD wrist strap

• Cables with connectors

• Any optional items ordered

Step 2 Check for damage and report any discrepancies or damage to your customer service representative. Have the following information ready:

• Invoice number of shipper (see packing slip)

• Model and serial number of the damaged unit

• Description of damage

• Effect of damage on the installation

Step 3 Make sure that the fan tray and power supplies all use the same direction of airflow.

• Port-side exhaust airflow modules do not have a black stripe across the front of the module.

• Port-side intake airflow modules have a black stripe across the front of the module.

Chapter 2 Installing a Cisco Nexus Fabric Extender Grounding the System

To install the device in a cabinet or rack using the rack-mount kit provided with the device, follow these steps:

Step 1 Install the front rack-mount brackets as follows:

a. Position a front rack-mount bracket against the chassis and align the screw holes. Attach the front rack-mount bracket to the chassis with six of the M4 screws.

b. Repeat with the other front rack-mount bracket on the other side of the device.

Step 2 Install the rack-mount guides on the device as follows:

a. Position one of the rack-mount brackets against the side of the device and align the screw holes. Attach the bracket to the device with two of the flat-head M4 screws.

b. Repeat with the other rack-mount bracket on the other side of the device.

Step 3 Attach the slider rails to the rack. Use two 12-24 screws or two 10-32 screws, depending on the rack rail thread type. For racks with square holes, insert the 12-24 cage nuts in position behind the mounting holes in the slider rails.

a. Repeat with the other slider rail on the other side of the rack.

b. Use the tape measure and level to verify that the rails are horizontal and at the same height.

Step 4 Insert the device into the rack as follows:

a. Using both hands, position the device with the back of the device between the port side exhaust posts of the rack.

b. Align the two rack-mount guides on either side of the device with the slider rails installed in the rack. Slide the rack-mount glides onto the slider rails, and then gently slide the device all the way into the rack. If the device does not slide easily, try realigning the rack-mount glides on the slider rails.

Step 5 Stabilize the device in the rack by attaching the front rack-mount brackets to the front rack-mounting rails as follows:

a. Insert two screws (12-24 or 10-32, depending on the rack type) through the cage nuts and the holes in one of the front rack-mount brackets and into the threaded holes in the rack-mounting rail.

b. Repeat for the front rack-mount bracket on the other side of the device.

Grounding the SystemThis section describes the need for system grounding and explains how to prevent damage from electrostatic discharge.

This section includes the following topics:

• Proper Grounding Guidelines, page 2-8

• Preventing Electrostatic Discharge Damage, page 2-9

• Establishing the System Ground, page 2-13

• Required Tools and Equipment, page 2-13



Proper Grounding GuidelinesGrounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you properly ground systems during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data corruption. Table 2-3 lists some general grounding practice guidelines.

Table 2-3 Proper Grounding Guidelines

EnvironmentElectromagnetic Noise Severity Level Grounding Recommendations

Commercial building is subjected to direct lightning strikes.

For example, some places in the United States, such as Florida, are subject to more lightning strikes than other areas.

High All lightning protection devices must be installed in strict accordance with manufacturer recommendations. Conductors carrying lightning current should be spaced away from power and data lines in accordance with applicable recommendations and codes. Best grounding recommendations must be closely followed.

Commercial building is located in an area where lightning storms frequently occur but is not subject to direct lightning strikes.

High Grounding recommendations must be closely followed.

Commercial building contains a mix of information technology equipment and industrial equipment, such as welding.

Medium to high Grounding recommendations must be closely followed.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment. This installation has a history of malfunction due to electromagnetic noise.

Medium Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the affected equipment. Grounding recommendations must be closely followed.



Note In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or local laws and regulations.

Note Always ensure that all of the devices are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.

Preventing Electrostatic Discharge DamageElectrostatic discharge (ESD) damage, which can occur when modules or other Field Replaceable Units (FRUs) are improperly handled, results in intermittent or complete failures. Devices consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD grounding strap when handling modules.

For preventing ESD damage, follow these guidelines:

• Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin.

• ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All Cisco Nexus 2000 Series FEX chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the port side exhaust panel. We recommend that you use a personal ESD grounding strap equipped with a banana plug.

• If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.

New commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.

Low Electromagnetic noise problems are not anticipated, but installing a grounding system in a new building is often the least expensive route and the best way to plan for the future. Grounding recommendations should be followed as closely as possible.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.

Low Electromagnetic noise problems are not anticipated, but installing a grounding system is always recommended. Grounding recommendations should be followed as much as possible.

Table 2-3 Proper Grounding Guidelines

EnvironmentElectromagnetic Noise Severity Level Grounding Recommendations



Note This system ground is also referred to as the network equipment building system (NEBS) ground.

• If your chassis does not have the system ground attached, you must install the system ground lug. See the“Establishing the System Ground” section on page 2-13 for installation instructions and location of the chassis system ground pads.

Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis.

After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:

Step 1 Attach the ESD wrist strap to your bare skin as follows:

a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.

b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows (see Figure 2-1 and Figure 2-2):

a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.

Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.

b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.



Figure 2-1 shows how to attach the ESD wrist strap to the system ground lug screw for the Cisco Nexus 2000 Series FEX.

In addition, follow these guidelines when handling these devices:

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

• Place a removed component board-side-up on an antistatic surface or in a static-shielding container. If you plan to return the component to the factory, immediately place it in a static-shielding container.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

Establishing the System GroundThis section describes how to connect a system ground to the Cisco Nexus 2000 and 2300 Series FEXs.

Note This system ground is also referred to as the network equipment building system (NEBS) ground.

You must use the system (NEBS) ground on AC-powered systems if you are installing this equipment in a U.S. or European Central Office.

The system (NEBS) ground provides additional grounding for EMI shielding requirements and grounding for the low-voltage supplies (DC-DC converters) on the devices and is intended to satisfy the Telcordia Technologies NEBS requirements for supplemental bonding and grounding connections. You must observe the following system grounding guidelines for your chassis:

• You must install the system (NEBS) ground connection with any other rack or system power ground connections that you make. The system ground connection is required if this equipment is installed in a U.S. or European Central Office.

• You must connect both the system (NEBS) ground connection and the power supply ground connection to an earth ground. The system (NEBS) ground connection is required if this equipment is installed in a U.S. or European Central Office.

• You do not need to power down the chassis because the Cisco Nexus FEX is equipped with AC-input power supplies.

Required Tools and EquipmentTo connect the system ground, you need the following tools and materials:

• Grounding lug—A two-hole standard barrel lug that supports up to 6 AWG wire. This lug is supplied as part of accessory kit.

• Grounding screws—Two M4 x 8mm (metric) pan-head screws. The screws are supplied as part of the accessory kit.

• Grounding wire—Not supplied as part of the accessory kit. The grounding wire should be sized according to local and national installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper conductor is required for U.S. installations. Commercially available 6 AWG wire is recommended. The length of the grounding wire depends on the proximity of the device to proper grounding facilities.

• No. 1 Phillips screwdriver.

• Crimping tool to crimp the grounding wire to the grounding lug.

• Wire-stripping tool to remove the insulation from the grounding wire.


Chapter 2 Installing a Cisco Nexus Fabric Extender Grounding the Chassis

Grounding the ChassisThe chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug.

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046

Caution We recommend that you ground the chassis, even if the rack is already grounded.

Caution You must ground all power supplies. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.


Caution Grounding the chassis is required if you are using DC power supplies, even if the rack is already grounded. A grounding pad with two threaded M4 holes is provided on the chassis for attaching a grounding lug. The ground lug must be NRTL listed. In addition, the copper conductor (wires) must be used and the copper conductor must comply with the NEC code.

To attach the grounding lug and cable to the chassis, follow these steps:

Step 1 Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the grounding cable.

Step 2 Insert the stripped end of the grounding cable into the open end of the grounding lug.

Step 3 Use the crimping tool to secure the grounding cable in the grounding lug.

Step 4 Remove the adhesive label from the grounding pad on the chassis.

Step 5 Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4 screws with washers through the holes in the grounding lug and into the grounding pad.

Step 6 Ensure that the lug and cable do not interfere with other equipment.

Step 7 Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure adequate earth ground.

Starting the Cisco Nexus Fabric ExtenderThis section describes how to power up the device and verify the hardware operation.

• Removing and Installing a Fan, page 2-19

• Removing and Installing the Fan Tray, page 2-21

• Removing the Cisco Nexus Fabric Extender, page 2-22

Caution To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by the carrier edges only.

Removing and Installing Power SuppliesThe Cisco Nexus 2000 Series FEX supports two power supplies, but the FEX uses only one power supply for operations. The other power supply is for redundancy.

Caution Whenever you replace a power supply, make sure that it has the same direction of airflow as the rest of the module in the switch (all fan tray and power supply modules must have the same direction of airflow and the same color designation for the airflow direction or else the switch can over heat and shut down.

http://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html



Note If you power up a FEX with power supply and fan tray modules that have different directions of airflow, an error condition will occur and the switch can over heat and shut down. With this error condition, you must shut down the switch to replace the modules that do not take in cool air from the cold aisle. After you ensure that all of the modules have the same direction of airflow and that they take in cooling air from the cold aisle, you can power up the FEX.


• Removing an AC Power Supply, page 2-17

• Installing an AC Power Supply, page 2-17

• Removing a DC Power Supply, page 2-18

• Installing a DC Power Supply, page 2-19

Note You can replace a faulty power supply while the system is operating if the other power supply is functioning.

Removing an AC Power Supply

Caution If you are using the Cisco Nexus 2000 or 2300 Series FEX with one power supply, removing the power supply causes the device to shut down. If you are using two power supplies and you remove one of them, the device continues to operate.

To remove an AC power supply, follow these steps:

Step 1 Pull the power cord out from the power receptacle on the power supply.

Step 2 Release the power supply from the chassis as follows:

• If you are removing a power supply from a Cisco Nexus 2148T chassis, loosen the captive screw and then pull the power supply part way out of the chassis.

• If you are removing a power supply from a Cisco Nexus 2248T, 2232PP, or 2224TP chassis, push and hold the thumb latch to the left and pull the power supply part way out of the chassis.

Step 3 Place your other hand under the power supply to support it while you slide it out of the chassis.

Step 4 If the power supply bay is to remain empty, install a blank power supply filler panel.

Installing an AC Power Supply

Caution Be sure that the power supply that you are installing has the same airflow direction as the fan tray module and the other power supply. Either all of the modules must have port-side exhaust airflow (blue or no color on the front of the module) or all of the modules must have port-side intake airflow (red or black color on the front of the module). To prevent over heating, the switch does not support more than one airflow direction for the modules in the chassis.



To install a power supply, follow these steps:

Step 1 Ensure that the system (earth) ground connection has been made for the chassis. For ground connection instructions, see the “Grounding the System” section on page 2-7.

Step 2 If the power supply bay has a filler panel, remove it from the slot as follows:

• If you are removing a filler panel from a Cisco Nexus 2248TP, 2232PP, or 2224TP FEX, push its thumb latch to the left and pull the panel out of the chassis.

• If you are removing a filler panel from a Cisco Nexus 2148T FEX, loosen its captive screw, and then pull the panel out of the power supply bay.

Step 3 Hold the replacement power supply by its handle and position it so that the captive screw is on the left, and then slide it into the power supply bay, ensuring that the power supply is fully seated in the bay.

Step 4 Secure the power supply to the chassis as follows:

• If you are installing a Cisco Nexus 2248TP, 2232PP, or 2224TP FEX, make sure that the thumb latch engages with the chassis so that the power supply is held in the slot.

• If you are installing a Cisco Nexus 2148T, fasten the power supply to the chassis by screwing its captive screw into its hole in the chassis and tightening it.

Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco Nexus 2000 Series FEX to your outlet receptacle. See the “Jumper Power Cord” section on page C-9.

Step 5 Connect the other end of the power cable to an AC power source.

Caution In a system with dual power supplies, connect each power supply to a separate power source. If a power source failure occurs, the second source will most likely still be available.

Step 6 Verify power supply operation by checking that the power supply LED is green. For information about what the power supply LEDs indicate, see the “Power Supply Status” section on page E-3.

Removing a DC Power Supply

Caution If you are using the Cisco Nexus 2200 platform FEX with one DC power supply, removing the power supply causes the device to shut down. If you are using two power supplies and you remove one of them, the device continues to operate.

To remove a DC power supply, follow these steps:

Step 1 Shut off the DC power to the power supply at the circuit breaker. Make sure that both LEDs are off.

Step 2 Unfasten the positive power cable from the right terminal.

Step 3 Unfasten the negative power cable from the left terminal.

Step 4 Press the thumb latch to disengage the power supply from the chassis and use the handle to pull it part way out of the chassis.



Step 5 Place your other hand under the power supply to support it while you slide it out of the chassis. Place the power supply on an antistatic surface.

Step 6 If the power supply bay is to remain empty, install a blank power supply filler panel.

Installing a DC Power Supply

In a system with dual power supplies, connect each power supply to a separate power source. If a power source failure occurs, the second source will most likely still be available.

Caution Be sure that the power supply that you are installing has the same airflow direction as the fan tray module and the other power supply. Either all of the modules must have port-side exhaust airflow (blue or no color on the front of the module) or all of the modules must have port-side intake airflow (red or black color on the front of the module). To prevent over heating, the switch does not support more than one airflow direction for the chassis.

To install a power supply, follow these steps:

Step 1 Ensure that the system (earth) ground connection has been made for the chassis. For ground connection instructions, see the “Grounding the System” section on page 2-7.

Step 2 If the power supply bay has a filler panel, push and hold the thumb latch to the left, and then slide the filler panel out of the power supply bay.

Step 3 Hold the replacement power supply by the handle and position it so that the thumb latch is on the right, and then slide it into the power supply bay, ensuring that the power supply is fully seated in the bay.

Step 4 Engage the thumb latch so that the power supply is firmly held in place in its slot.

Step 5 Fasten the positive cable from the power source to the right terminal on the power supply. This terminal is labeled positive (+) on newer power supplies and is labeled incorrectly as negative (-) on the first power supplies sold.

Step 6 Fasten the negative cable from the power source to the left terminal on the power supply. This terminal is labeled negative (-) on newer power supplies and is labeled incorrectly as positive (+) on the first power supplies sold.

Step 7 Turn on the power at the circuit breaker.

Step 8 Verify power supply operation by checking that the power supply LED is green. For information about what the power supply LEDs indicate, see the “Power Supply Status” section on page E-3.

Removing and Installing a FanThe Cisco Nexus 2300 Series FEXs support three fans, but the FEX needs only two fans for operation. The other fan is for redundancy. Individual fans are designed to be removed and replaced while the system is operating, without causing an electrical hazard or damage to the system.

If you are replacing a fan tray on a Cisco Nexus 2200 Series FEX, or Cisco Nexus 2148T FEX, see the “Removing and Installing the Fan Tray” section on page 2-21.



Caution Be sure that the fan that you are installing has the same airflow direction as the other fans and power supply modules in the same chassis. Either all of the modules must have port-side exhaust airflow (a blue or no color on the front of the module) or all of the modules must have port-side intake airflow (red or black color on the front of the module). If the modules have different airflow directions in the same chassis, an error condition occurs, the switch can over heat, and the switch can shut down.

Note If you power up a FEX with power supply and fan modules that have different directions of airflow, an error condition will occur and the switch can over heat and shut down. With this error condition, you must shut down the switch to replace the modules that do not take in cool air from the cold aisle. After you ensure that all of the modules have the same direction of airflow and take in cooling air from the cold aisle, you can power up the FEX.

To remove a fan, follow these steps:

Step 1 Pinch the two protruding tabs of the fan towards each other to release the latch and pull the fan outward.

Step 2 Pull the fan clear of the chassis and set it on an antistatic surface or repack it in packing materials.

Installing a Fan

To install a fan, follow these steps:

Step 1 Place the fan into the port-side exhaust chassis cavity so it rests on the chassis, and then push the fan into the chassis as far as it can go until it is latched in place.

Step 2 Listen for the fan if the device is powered on. You should immediately hear it operating. If you do not hear it, ensure that the fan is inserted completely in the chassis and the faceplate is flush with the outside surface of the chassis.

Step 3 Verify that the LED is green. If the LED is not green, the fan is faulty. If this problem occurs, contact your customer service representative for a replacement part.




Removing and Installing the Fan TrayThe Cisco Nexus 2200 Series FEXs, and Cisco Nexus 2148T FEX, use a fan tray. The fan tray is designed to be removed and replaced while the system is operating without causing an electrical hazard or damage to the system, if the replacement is performed within 1 minute.

Caution Be sure that the fan tray that you are installing has the same airflow direction as the other fan tray and power supply modules in the same chassis. Either all of the modules must have port-side exhaust airflow (a blue or no color on the front of the module) or all of the modules must have port-side intake airflow (red or black color on the front of the module). If the modules have different airflow directions in the same chassis, an error condition occurs, the switch can over heat, and the switch can shut down.

Note If you power up a FEX with power supply and fan tray modules that have different directions of airflow, an error condition will occur and the switch can over heat and shut down. With this error condition, you must shut down the switch to replace the modules that do not take in cool air from the cold aisle. After you ensure that all of the modules have the same direction of airflow and take in cooling air from the cold aisle, you can power up the FEX.

• Removing an SFP+ Transceiver, page 3-3

Installing an SFP+ Transceiver

To install an SFP+ transceiver, follow these steps:

Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.

Step 2 Remove the dust cover from the port cage.

Step 3 Remove the dust cover from the port end of the transceiver.

Step 4 Insert the transceiver into the port as follows:

• If the transceiver has a Mylar tab latch, position the transceiver with the tab on the bottom, and then gently insert the transceiver into the port until it clicks into place.

• If the transceiver has a bale clasp latch, position the transceiver with the clasp on the bottom, close the clasp by pushing it up over the transceiver, and then gently insert the transceiver into the port until it clicks into place.

Caution If the transceiver does not install easily, ensure that it is correctly positioned and the tab or clasp are in the correct position before continuing.

Note If you cannot install the cable into the transceiver, insert or leave the dust cover in the cable end of the transceiver.

Removing an SFP+ Transceiver

To remove an SFP+ transceiver, follow these steps:


Step 2 If a cable is installed in the transceiver, do one of the following:

a. Record the cable and port connections for later reference.

b. Press the release latch on the cable, grasp the connector near the connection point, and gently pull the connector from the transceiver.

c. Insert a dust plug into the cable end of the transceiver.

Caution If the transceiver does not remove easily in the next step, push the transceiver completely in and then ensure that the latch is in the correct position before continuing.

Step 3 Remove the transceiver from the port as follows:

• If the transceiver has a Mylar tab latch, gently pull the tab straight out (do not twist), and then pull the transceiver out of the port.



• If the transceiver has a bale clasp latch, open the clasp by pressing it downward, and then pull the transceiver out of the port.

Note If you have difficulty removing a bale clasp SFP+ transceiver, you should reseat it by returning the bale clasp to the up position. Press the SFP+ transceiver inward and upward into the cage. Next, lower the bale clasp and pull the SFP+ transceiver straight out with a slight upward lifting force (see Figure 3-1). Be careful not to damage the port cage during this process.

Figure 3-1 Alternate Removal Method for Bale Clasp SFP+ Transceivers

Step 4 Insert a dust cover into the port end of the transceiver and place the transceiver on an antistatic mat or into a static shielding bag if you plan to return it to the factory.

Step 5 If another transceiver is not being installed, protect the optical cage by inserting a clean cover.

Removing and Installing Cables into SFP+ TransceiversThis section describes how to remove and install cables into and from SFP+ transceivers.

Caution To prevent damage to the copper cables, do not place more tension on them than the rated limit and do not bend to a radius of less than 1 inch if there is no tension in the cable, or 2 inches if there is tension in the cable.

Removing a Cable from an SFP+ Transceiver

Caution When pulling a cable from a transceiver, grip the body of the connector. Do not pull on the jacket sleeve, because this action can compromise the fiber-optic termination in the connector.

Caution If the cable does not remove easily, ensure that any latch present on the cable has been released before continuing.

To remove the cable, follow these steps:


Step 2 Press the release latch on the cable, grasp the connector near the connection point, and gently pull the connector from the transceiver.

Step 3 Insert a dust plug into the cable end of the transceiver.

Step 4 Insert a dust plug onto the end of the cable.

Installing a Cable into an SFP+ Transceiver

Caution To prevent possible damage to the cable or transceiver, install the transceiver in the port before installing the cable in the transceiver.

To install a cable into a transceiver, follow these steps:


Step 2 Remove the dust cover from the connector on the cable.

Step 3 Remove the dust cover from the cable end of the transceiver.

Step 4 Align the cable connector with the transceiver and insert the connector into the transceiver until it clicks into place.

Caution If the cable does not install easily, ensure that it is correctly positioned before continuing.

For instructions on verifying connectivity, see the Cisco Nexus 2000 Series Fabric Extender Software Configuration Guide.



Maintaining SFP+ Transceivers and CablesYou must keep SFP+ transceivers clean and dust free to maintain high signal accuracy and prevent damage to the connectors. Attenuation (loss of light) is increased by contamination and should be below 0.35 dB.

Follow these maintenance guidelines:

• SFP+ transceivers are static sensitive. To prevent ESD damage, wear an ESD-preventive wrist strap that is connected to the chassis.

• Do not remove and insert a transceiver more often than is necessary. Repeated removals and insertions can shorten its life.

• Keep all optical connections covered when not in use. If they become dusty, clean before using to prevent dust from scratching the fiber-optic cable ends.

• Do not touch ends of connectors to prevent fingerprints and other contamination.

• Clean regularly; the required frequency of cleaning depends upon the environment. In addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning techniques can be effective; refer to your site’s fiber-optic connection cleaning procedure.

• Inspect routinely for dust and damage. If damage is suspected, clean and then inspect fiber ends under a microscope to determine if damage has occurred.

ACabinet and Rack Installation

This appendix provides the requirements for cabinet and rack installation and includes the following sections:

• Cabinet and Rack Requirements, page A-1

• Cable Management Guidelines, page A-3

Cabinet and Rack RequirementsThis section provides the requirements for the following types of cabinets and racks, assuming an external ambient air temperature range of 0 to 104oF (0 to 40oC):

• Standard perforated cabinets

• Solid-walled cabinets with a roof fan tray (bottom to top cooling)

• Standard open racks

Note If you are selecting an enclosed cabinet, we recommend one of the thermally validated types, either standard perforated or solid-walled with a fan tray.

Note Do not use racks that have obstructions (such as power strips), because the obstructions could impair access to field-replaceable units (FRUs).


• General Requirements for Cabinets and Racks, page A-1

• Requirements Specific to Perforated Cabinets, page A-2

• Requirements Specific to Standard Open Racks, page A-2

General Requirements for Cabinets and RacksThe cabinet or rack must be one of the following types:

• Standard 19-in. (48.3 cm) (four-post EIA cabinet or rack, with mounting rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992). See the “Requirements Specific to Perforated Cabinets” section on page A-2.


Appendix A Cabinet and Rack Installation Cabinet and Rack Requirements

The cabinet or rack must also meet the following requirements:

• The minimum vertical rack space per Cisco Nexus 2000 Series FEX chassis or Cisco Nexus 2300 Series FEX chassis must be one RU (rack units), equal to 1.75 inches (4.4 cm).

• The width between the rack-mounting rails must be at least 17.75 inches (45.0 cm) if the rear of the device is not attached to the rack. For four-post EIA racks, this measurement is the distance between the two port side exhaust rails.

• For four-post EIA cabinets (perforated or solid-walled), the requirements are as follows:

– The minimum spacing for the bend radius for fiber-optic cables should have the port side exhaust-mounting rails of the cabinet offset from the port side exhaust door by a minimum of 3 inches (7.6 cm).

– The distance between the outside face of the port side exhaust mounting rail and the outside face of the back mounting rail should be 23.0 to 30.0 inches (58.4 to 76.2 cm) to allow for rear-bracket installation.

– A minimum of 2.5 inches (6.4 cm) of clear space should exist between the side edge of the chassis and the side wall of the cabinet. No sizable flow obstructions should be immediately in the way of chassis air intake or exhaust vents.

Note Optional jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on page C-9.

Requirements Specific to Perforated CabinetsA perforated cabinet is defined as a cabinet with perforated port side exhaust and rear doors and solid side walls. In addition to the requirements listed in the “General Requirements for Cabinets and Racks” section on page A-1, perforated cabinets must meet the following requirements:

• The port side exhaust and rear doors must have at least a 60 percent open area perforation pattern with at least 15 square inches (96.774 square cm) of open area per rack unit of door height.

• The roof should be perforated with at least a 20 percent open area.

• The cabinet floor should be open or perforated to enhance cooling.

The Cisco R Series rack conforms to these requirements.

Requirements Specific to Standard Open RacksIn addition to the requirements listed in the “General Requirements for Cabinets and Racks” section on page A-1, if mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets the following requirements:

• The minimum vertical rack space per chassis must be two rack units (RU), equal to 3.47 inches (8.8 cm).

• The horizontal distance between the chassis and any adjacent chassis should be 6 inches (15.2 cm), and the distance between the chassis air vents and any walls should be 2.5 inches (6.4 cm).

DTroubleshooting Hardware Components

This chapter describes how to identify and resolve problems that might occur with the hardware components of the Cisco Nexus 2000 Series Fabric Extender (FEX) or Cisco Nexus 2300 Series FEX. It includes the following sections:

• Overview, page D-1

• SNMP Traps, page D-1

• Device Hardware Guidelines, page D-2

• Contacting Customer Service, page D-3

OverviewThe key to success when troubleshooting the system hardware is to isolate the problem to a specific system component. The first step is to compare what the system is doing to what it should be doing. Because a startup problem can usually be attributed to a single component, it is more efficient to isolate the problem to a subsystem rather than troubleshoot each separate component in the system.

Problems with the initial power up are often caused by a module that is not firmly connected to the backplane or a power supply that has been disconnected from the power cord connector.

Overheating can also cause problems with the system, though typically only after the system has been operating for an extended period of time. The most common cause of overheating is the failure of a fan tray.

SNMP TrapsYou can set SNMP traps to monitor fans, power supplies, and temperature settings, or to test a call home application. Use the following commands to set SNMP traps:

• test pfmtest-SNMP-trap fan

• test pfmtest-SNMP-trap power supply

• test pfmtest-SNMP-trap temp-sensor


Appendix D Troubleshooting Hardware Components Device Hardware Guidelines

Device Hardware GuidelinesUse the recommendations in this section to ensure the proper installation, initialization, and operation of the device. This section includes the following topics:

• Installation, page D-2

• Initialization, page D-2

• Device Operation, page D-2

InstallationWhen installing the device, follow these best practices:

• Plan your site configuration and prepare the site before installing the chassis.

• Verify that you have the appropriate power supplies and fan trays for your chassis configuration. For each chassis, each module must have the same airflow direction. Either all modules have front-to-back airflow (no black stripe on the front) or all have back-to-front airflow (black stripe on the front). If you have modules that use different airflow directions in the same chassis, you will see an error message.

• Install the chassis following the rack and airflow guidelines in this publication.

• Verify that the chassis and DC power supplies are adequately grounded.

InitializationWhen the initial system boot is complete, verify the following:

• Power supplies are supplying power to the system.

• Fan trays are operating normally.

• The system software boots successfully. See the Cisco Nexus 2000 Series Fabric Extender Software Configuration Guide for information about booting the system and initial configuration task.

Device OperationTo ensure proper operation of your device, do the following:

• Make a copy of the running configuration to CompactFlash for a safe backup.

• Always enter the copy running-config startup-config command after you modify the running configuration and ensure that the system is operating properly.

• Never use the init system command unless you understand that you will lose the running and startup configuration as well as the files stored on bootflash:.

• Keep backup copies of the running kickstart and the system images on CompactFlash.


Appendix D Troubleshooting Hardware Components Contacting Customer Service

Contacting Customer ServiceIf you are unable to solve a startup problem after using the troubleshooting suggestions in this chapter, contact a customer service representative for assistance and additional instructions. Before you call, have the following information ready to help your service provider assist you as quickly as possible:

• Date that you received the device

• Chassis serial number (located on a label on the right of the rear panel of the chassis)

• Type of software and release number

• Maintenance agreement or warranty information

• Brief description of the problem

• Brief explanation of the steps that you have already taken to isolate and resolve the problem
